Computer Forensics MCQ Quiz

Computer forensics is indeed a branch of digital forensic science. Digital forensic science involves the collection, analysis, and preservation of digital evidence for legal purposes. Computer forensics specifically focuses on investigating and analyzing digital devices, such as computers, laptops, and mobile phones, to uncover evidence of cybercrime or other digital offenses. It involves techniques and tools to recover deleted or hidden data, trace network activities, and analyze digital artifacts. Therefore, the statement "Computer forensics is a branch of digital forensic science" is true.

Control is one of the three c's in computer forensics. In computer forensics, control refers to the ability to maintain and regulate access to digital evidence during the investigation process. It involves implementing measures to ensure the integrity and authenticity of the evidence, such as using write-blocking tools to prevent any changes to the original data. Control is crucial in preserving the evidentiary value of digital evidence and ensuring that it can be admissible in a court of law.

When first securing the area, the main priority is to ensure the safety of the crime scene. This involves taking necessary precautions to prevent contamination or tampering of evidence. By securing the area and making sure it is safe, investigators can then proceed to gather evidence without the risk of compromising its integrity. The other options, such as looking for evidence or making sure the computer is on, may be important steps in the investigation process, but they are secondary to ensuring the safety and integrity of the crime scene.

The correct answer is "Bring paper and an extra pencil." This is because paper and a pencil are not necessary equipment for recording video. The other options, such as using date/time, carrying extra batteries, and carrying extra memory, are all essential for preparing to record video.

Law enforcement is the best word that fits with the given definition of officials setting up a perimeter around a crime scene. Law enforcement refers to the organizations and individuals responsible for maintaining law and order, investigating crimes, and ensuring public safety. Setting up a perimeter is a common practice in crime scene management, where law enforcement officials establish a boundary around the area to preserve evidence, control access, and prevent contamination. This term specifically relates to the activities and responsibilities of law enforcement agencies and personnel in handling criminal incidents.

The scientific method involves a series of systematic steps to investigate and understand phenomena. The steps typically include raising a question, formulating hypotheses, testing the hypotheses through experiments or observations, and drawing conclusions based on the results. Waiting to test is not a step in the scientific method because it implies a lack of action or experimentation, which is essential for gathering data and verifying hypotheses.

The answer "Searching the crime scene" is not a record because it refers to an action or task rather than a documented record. The other options, such as "Chain of custody," "Documentation of the crime scene," and "Document your actions," all involve creating and maintaining written or recorded records of various aspects related to the crime scene or investigation.

The correct answer is "Leave it off" because when a computer is turned off, it means that it is not currently in use and should be left in that state. Turning it on or starting to type on it would imply that you want to use it, which contradicts the fact that it is turned off. Flipping the switch could also turn it on, so it is not the correct action to take when the computer is turned off.

Physical Forensics Discipline includes the analysis and interpretation of bloodstain patterns at crime scenes. This involves examining the size, shape, and distribution of bloodstains to determine the type of injury, the position of the victim and perpetrator, and the sequence of events. By studying bloodstains, forensic experts can reconstruct the crime scene and provide crucial evidence in criminal investigations.

The correct answer is "Your arrival time." This is because documenting something on audio means recording or capturing it in audio format. Your arrival time can be easily documented by verbally stating it and recording it using an audio device. Writing down information, zooming in on evidence, and capturing close-up images are all visual methods of documentation, not audio.

The investigator-in-charge is responsible for identifying and collecting electronic evidence. This involves locating and gathering digital information that may be relevant to the investigation. By collecting electronic evidence, the investigator can analyze and use it to support their findings and conclusions. It is an essential step in the investigative process to ensure that all relevant information is obtained and properly documented.

The answer depends on the context. If you’re a computer forensics investigator and you’ve just arrived at a scene, the best practice is to: D. Log the user off.

This is because shutting down or unplugging the computer might result in the loss of volatile data. However, if you’re not an investigator and you’ve found a computer that’s been left on, the most respectful thing to do would be to leave it as it is. 

A backup computer is essential in computer forensics for various purposes, including analyzing data without affecting the original system, testing forensic tools and techniques, and ensuring continuity of work in case of hardware or software failures. Having a backup computer allows forensic analysts to securely store and process digital evidence while minimizing the risk of data loss or corruption.

The correct answer is "investigation, investigating." In computer forensics, investigation is a crucial step in the life cycle. It involves gathering evidence, analyzing data, and identifying potential suspects. Investigating is the continuous process of examining and evaluating the collected evidence to uncover the truth and build a case. Both investigation and investigating are essential components of the computer forensics life cycle, as they help in identifying and resolving any digital crimes or security breaches.

The most important thing to keep track of is the date and time. This is crucial for various reasons such as scheduling appointments, meeting deadlines, organizing events, and maintaining a chronological record of activities. Having accurate and up-to-date information about the date and time ensures effective planning and coordination, enabling individuals and organizations to stay organized and meet their commitments efficiently.
